Hello,
What is the best way, with PostGres, to create a Unique Number Key
Generator?
For example, I have a STUDENTS table:
{
StudentNumber integer;
StudentName char[40];
...
}
Beginner in SQL, I think I must use Primary key or something like that, to
be sure StudentNumber is unique.
But, I want StudentNumber to be generated automatically, the user don't
worry in assigning a StudentNumber.
What is the best way to do that with PostGres-SQL ?
Thank you for your answers and sorry for my poor english,
